my friend has a Biostar NF61V Micro AM2 motherboard and theres no sound. Tried the speakers works fine with psp. tried drivers from both the usa website and the taiwan website. has this error when installing, so I'm wondering if it could be because of this. “Microsoft Bus Driver should be loaded in your system before installing Realtek HD Audio Driver" the front audio ports are not working too. and onboard audio has been enabled in bios too. thanks.
